GRAIN-CARRIER.

SPECIFICATION forming part of Letters Patent No. 483,617, dated October4, 1892.

Application iiled March 30, 1892.

To a/ZZ whom it may concern.:

Be it known that I, WILLIAM I-I. KNAPP, a citizen of the United States,residing at Kalamazoo, county of Kalamazoo, State of Michigan, haveinvented a new and useful Grain- Carrier, of which the following is aspecification.

This invention relates to that class ot graincarriers in which barsbearing teeth are carried by endlessbeltsor sprocket-chains around endpulleys in a manner that the teeth are always held at the same anglewhen traveling in both directions and when passing around the pulleys,so as to be thrust directly into and out of the grain. Such apparatusesare sometimes termed elevators and packers, as the same principle holdsgood for the three uses, and also in machines for carrying or elevatingother commodities and articles aside from grain.

The main object of this invention consists in certain improvements tomake more practical the use of long tooth-bars extending across thecarrier-frame, the power in a com struction embodying my improvementsbeing applied at both ends of said tooth-bars.

In the drawings forming a part of this speciication, Figure 1 is anelevation, parts being broken away; Fig. 2, a sectional elevation online 3 3 in Fig.` 1, looking from a point at the left; Fig. 3, a topview of Figs. 1 and 2 5 and Fig. l1 shows enlarged lettered details fromFig. 1, a portion being in section on line 2 2 in the lattennamed gure.

Referring to the lettered parts of the drawings, A represents a frame inwhich the several sprocket-wheels below described are revolubly mounted.On one side of the frame are two sets of sprocket-wheels D C and GI-I,the sprocket-wheels I) C being at one end of the frame and G H at theother. These sets of sprocket-wheels are on separated parallel planes,and one set jogs by the other, as in Fig. 1. The sprocket-wheels D Gcarry the sprocket-belt a and the sprocket-wheels C H carry the sprocket-belt c. The sprocket- Wheels l L on the opposite side of the frame Acarry a sprocket-beltf. The sprocket-wheels I L are the same distanceapart as the sprocket-wheels C H.

Transversely between the sprocket-belts f c is a series of tooth-bars m,having teeth o,

elbowed at each end in opposite directions,

Figs. 2 ard 3. The same number of arms v are employed as' there aretooth-bars m, and one elbow end of these arms n is rigidly attached tothe pivotal ends of the tooth-bars m, Figs. 1 and 4. The other elbow endof the arms fu is pivotally attached to the eyedlinks oi' itssprocket-belt a, Fig. 1, the same as the ends of the tooth-bars m arepivoted.P y

Power is first imparted, preferably, to the sprocket-wheels C H and thesprocket-belt c,

which they carry by any suitable connecting means, no such means beingherein shown,

since it will bc well understood. Motion is transmitted fromsprocket-belt oto sprocketbelt a through the connecting-arms o.

To prevent cramping by the tendency of the ends of the tooth-barsattached to sprocket beltfto lag behind, I provide a transverse shaft P,having sprocket-gears F and K, rigidly attached to the ends, Figs. 2 and3, and thus by means of sprocket-belt e on sprocketwheels E F andsprocket-belt on the sprocketwheels J K motion is imparted and powerapplied to the sprocket-belt f to carry along its end of the tooth-barsm, the same as do the sprocket-belts c atheir end of said tooth-bars. Inthis connection it should be observed that the sprocket-wheels D E arerigidly attached together, or to an axis common to both, as are thesprocket-Wheels I J as well.

In use the front face of the carrier-frame will be provided withseparate slats in the ordinary manner, on which slats the grain slideswhen being carried by the teeth o to the binding-deck above, said teethprojecting out through the longitudinal spaces between said slats. Noslats are here shown, since they are common in reaping-machines. Nobinding-deck is here shown,but is suiicientlycommon in relation tocarriers in like relation to be well understood.

The carrier in a reaping-machine is at an oblique angle instead ofperpendicular, as in Fig. 2; but this does not affect the inventionherein described.

IOO

In many reaping-machines it is necessary to carry the teeth of thetooth-bars lower than can1be done by the tooth-bars m, because, owing tothe construction of said machines, the sprocket-wheels L H in Fig. 1cannot be placed low enough to carry the tooth-bars m down to thegrain-platform, which is in the immediate rear of the cutter-bar, andupward from which grain-platform the carrier extends.

Itis not deemed necessary to show the grainplatform, because itslocation in a reapingmachine in its relation to the carrier which takesthe grain therefrom and carries it to the binding-deck aboveis-wellknown.

In order to carry the teeth lower than they can be carried by thetooth-bars m, as above stated, I employ supplemental 1 tooth-bars n,

c Fig. l, made somewhat shorter than the toothbars m, and attached tothe latter by means of arms a', attached to saidtoothbars m and to theends of the supplemental tooth-bars n, so that the latter; bars will beseparated from the former and run parallel therewith. By this means thesupplemental'tooth-bars nare of course carriedlowerthan the tooth-barsmcan be carried, and thus enable the teeth to gather grain from a pointlower than could the teeth of the tooth-bars fm.. Y.

While I have described sprocketwheels and sprocket-belts, of cou-rse anysuitable pulleys and belts may be employed, whether sprocket orotherwise. Carriers made on this principle may be employed in ahorizontal position or at any angle for carrying; or elevating anyarticle or commodity desirable.

The arrows in therdifterent figures show V the direction in which thesprocket-belts move.

- Referring to Figs. 1 and 2, supposing the apparatus to be inoperation, the outer toothbars, with their teeth, (the Vright-hand onesin Fig. 2,) are moving upward, andwhen they i pass aroundrthesprocket-wheels C H said `F J K andY sprocket-wheels e fi,Y of coursegearing or any other suitable mechanism may be substituted, although themeans here shown are preferable. i

I have said that power is preferably first applied directly to thepulleys CV H and theirV belt c, and this is desirable, because thetoothbars are attached at one end to said belt c; but the power may befirst applied to the sprocket-wheels D G and their sprocketbelt a, inwhich case the power is transmitted to the belt c through the arms o,and to-.the

belt f, as before stated, through the shaft P and its connecting means.In regard to the` jogging 'of the bolts c a one by the other, thedistance of said jog is the same as thelength of the arms fu, soVV thatwhen these arms pass around the pulleys C and D at one end and H and Gat theother end said arms are kept at the same angle as when moving fromone end of the carrier tothe other, said arms being thus held by thebelt a, to which they are pivoted, and it follows that since these armso are rigidly attached to the tooth-bars m said tooth-bars are alwaysheld in the same position, so that their Yteeth are always carried atthe same angle, as before stated.

Vhile I Vhave stated that this carrier may be located at anyangle-horizontal, perpendicular, or otherwisedit may also be employed ina reverse position, end for end.

Having thus described my invention, what I claim as new,and desire tosecure by Letters Patent of the United States, is- 1 Y 1. A carriercomprising a Ysuitable frame, a series of transverse bars provided withteeth, a traveling belt and pulleys at each side, to which belts theends of the tooth-bars are pivotally attached, arms elbowed at the endsin opposite directions, one end of said arm being rigidly attached tothe tooth-bars, a

traveling belt to which the other ends of said arms are pivotallyattached, this latter-named belt being jogged by the other belt at thesame side of the carrier, and suitable means for transmitting power fromone side of the carrier to the other side of the carrier, substantiallyas set forth. Y

2. A carrier comprising a suitable frame, a

supplemental bars provided with teeth and attached to the former-namedtooth-bars, a traveling belt and pulleys at each side, to which beltsthe ends of the tooth-bars are pivotally attached, arms elbowed at theends,

which belt the ends of the tooth-bars are pivoted, two parallelbeltsjogging by each other at-the other side of the carrier and to one ofwhich belts the other ends of the tooth-bars are pivoted, the elbow-armsbetween said belts, one end of said arm being rigidly attached to thetoothbars and the other end pivoted to the outermost belt, wheels orpulleys upon which said belts are mounted, wheels or pulleys at one endof the carrier for transmitting power, one being rigidly attached to thewheel or pulley ofthe belt to which the elbow-arms are pivoted and theother rigidly attached to the wheel or pulley of the belt at IOO Yseriesof transverse bars provided with teeth,
